Basic rule

1. Residential design should meet the requirements of urban planning and residential area planning, and use land and space economically, reasonably and effectively.

2, residential design should make the building and the surrounding environment in harmony, and should reasonably organize convenient and comfortable living space.

3, residential design should be people-oriented, in addition to meet the general living requirements, but also to meet the needs of special groups such as the elderly, the disabled.

4. Residential design should meet the requirements of sunshine, natural lighting, ventilation, sound insulation and so on.

5, residential design must meet the requirements of energy saving, residential buildings should be able to make rational use of energy. According to the local energy conditions, the energy supply mode combining conventional energy and renewable energy should be adopted.

6, residential design should be standardized, modular and diversified, and should actively adopt new technologies, new materials, new products, and actively promote industrial design, construction technology and modular application technology.

7. The structural design of the house should meet the requirements of safety, applicability and durability.

8, residential design should comply with the provisions of the relevant fire code, and should meet the requirements of safe evacuation.

9. The residential design should meet the basic requirements of effective function, safe operation and convenient maintenance of the equipment system, and reserve a reasonable installation position for related equipment.

10, the residential design should meet the recent use requirements, taking into account the possibility of future transformation.

Exponential calculation

1, the following technical and economic indicators shall be calculated for residential design:

—— usable area of each functional space (m);

-usable area of the suite (m2/suite);

-balcony area (m/set);

-The total construction area of the apartment (m2/set);

-Total construction area of residential buildings (m).

2, the calculation of residential technical and economic indicators, shall meet the following requirements:

1) The usable area of each functional space shall be equal to the horizontal projection area enclosed by the inner surface of the wall of each functional space;

2) The usable area in the suite shall be equal to the sum of usable areas of all functional spaces in the suite;

3) The balcony area should be equal to the sum of the balcony areas in the suite; The balcony area should be calculated according to half of the projected net area of the structural floor;

4) The total construction area of Xing Tao should be equal to the sum of the usable area, corresponding construction area and balcony area of Xing Tao;

5) The total construction area of residential buildings should be equal to the sum of the total construction area of each apartment in the whole building.

3. The calculation of usable area inside the suite shall meet the following requirements:

1) The usable area of the suite shall include the sum of usable areas of bedroom, living room (hall), dining room, kitchen, bathroom, lobby, aisle, storage room and closet;

2) Stairs in duplex apartments should be included in the indoor usable area according to the sum of usable areas of natural floors;

3) Chimneys, ventilation pipes, tube wells, etc. Should not be included in the usable area of the suite;

4) The usable area in the suite is calculated according to the structural wall area; If there is a composite insulation layer, it should be calculated according to the surface size of the composite insulation layer;

5) When using the space inside the sloping roof, the space with the clear height between the lower surface of the roof panel and the ground below 1.20m should not be calculated as the usable area, and the space with the clear height between 1.20m and 2. 10m should be calculated as12, and the clear height should exceed 2. 10m. There is no structural top floor on the sloping roof, and when the sloping roof space cannot be used, its usable area should not be calculated;

6) The usable area in the sloping roof should be included in the usable area in the suite.

4. The calculation of the total construction area of Xing Tao shall meet the following requirements:

1) should be calculated according to the sum of the horizontal projection areas surrounded by the outer surface of the external wall structure of each floor of the whole building and the outer edge of the column. When the external wall has an external insulation layer, it should be calculated according to the external area of the insulation layer;

2) The calculated ratio should be the usable area of the whole building divided by the residential building area;

3) The total construction area of Xing Tao should be equal to the interior area divided by the calculated ratio, plus the balcony area of Xing Tao.

5, the calculation of residential building floors shall meet the following requirements:

1) When the height of each floor of a residential building does not exceed 3.00 m, the number of floors shall be counted as natural floors;

2) When the residence and other functional spaces are located in the same building, the number of floors of the residence and other functional spaces should be superimposed to calculate the number of floors of the building. When the height of one or more floors in a building is greater than 3.00 m, all floors above 3.00 m should be divided by 3.00 m to convert the number of floors. When the remainder is less than 1.50 m, the excess part shall not be included in the number of building floors. When the remainder is greater than or equal to 1.50 m, the excess part shall be calculated as 1 layer.

3) The overhead floor and equipment floor with a height less than 2.20 m should not be included in the natural floor;

4) Semi-basement with outdoor design less than 2.20m above the ground should not be included in the natural floor on the ground.
